The late Phil Fisher was one of the great investors of all time and the author of the classic book Common Stocks and Uncommon Profits. Fisher started his money management firm, Fisher & Co., in 1931 and over the next seven decades made tremendous amounts of money for his clients. For example, he was an early investor in semiconductor giant Texas Instruments TXN, whose market capitalization recently stood at well over $40 billion. Fisher also purchased Motorola MOT in 1955, and in a testament to long-term investing, held the stock until his death in 2004.
